Description c 2022-10-13 23:20:27 UTC 
Attempting to run `hostname -i` on an Alpine Linux container in an IPv6 Kubernetes installation fails to resolve the host, despite the ip and hostname being present in /etc/hosts. On the other hand, this works in an Ubuntu container.

Presumably this is due to the use of gethostbyname, rather than getaddrinfo.
